Tangible Lights is a childrens’ building set made from cylindrical pieces that light up and change colors when you stack them together. Each block is embedded with an LED powered by a coin cell that can produce 160 hours of playing time, and embedded magnets make them snap together easily.

Putting a green spin on the project, all the Tangible Lights are constructed from reused milk jug containers. It’s a project that provides a hands-on, interactive learning experience for kids. Based on the video above, it looks like kids had a blast constructing with them, as I’m sure they will this year at World Maker Faire.

In addition to being an online editor for MAKE Magazine, Michael Colombo works in fabrication, electronics, sound design, music production and performance (Yes. All that.) In the past he has also been a childrens’ educator and entertainer, and holds a Masters degree from NYU’s Interactive Telecommunications Program.
